And you're entitled to that opinion CS. However, I'm also entitled to mine.
Like I said, indoors, these things could be quite useful, and if limited (and supplied to both teams) wouldn't become an unbalancing factor. I'm not saying they would see use every game, but they would certainly be something thrown into the mix to spice it up now and then.
Let's face it - once you've played dozens of games in the same space, it can get a little stale. If you're limited to that same space (as my group is - we don't have any place to play that suits our needs other than the church), you have to throw a new game variant or a new type of weapon into the mix every now and then.
Case in point - we use these air rockets
, each supplied with two rockets and a holster/quiver, as "rocket launchers". Rather than some easy-to-abuse/refuse "blast radius", we just say that hits from the rockets count until they stop moving, wheras other shots (from darts) are deemed dead once they hit anything (a wall, ceiling, player, etc). This, combined with the fact that nothing else we use can outrange these things, makes them desirable weapons that are difficult to use and don't remotely unbalance the game, but add a slightly different aspect of play to the game (as well as granting bragging rights to anyone who scores a kill with them). For instance, they can be launched over the whole distance of the auditorium, and even potentially score a hit on people hiding behind things via indirect fire & bouncing.
I have considered adding some ball blasters to the mix, with the same "counts until it stops" rule for more variety.
